The drone flew nimbly while throwing silver nitrate solution, and in the blink of an eye, the nitric acid solution in the bomb shelter rose to knee-high height.

Vampires of the Earl and Marquis levels had to struggle to maintain their magic in order to ensure that the dark shield would not be eroded by the solution and dissolve their limbs.

Prince Revorno, Shchedrin and Si Te, the two dukes, were a little relaxed, and kept wielding the Shadow Demon Sword to relieve his subordinates with the blade, "Your Majesty, quickly find a way!"

"Hold on, I'll kill those bastards. "Each of the 13 princes of the Brotherhood has a canopy stone, which protects him from the sun. At the moment, Revorno is the only one of all who can face the sun. He took on the form of a blood clan and flapped his wings and flew towards the mouth of the cave.

His actions were quickly fed back to the ground through the drone, and Ao Ding, who was guarding the exit, drove the spiritual power, secretly causing the silver nitrate solution in the internal "um......" bomb shelter to make big waves.

Solution is liquid after all, as the descendant of the dragon who dominates the water, the black dragon Ao Ding is born with a strong ability to drive water, and the spiritual power urges the silver nitrate waves in the cave to roll, like the deep sea under a storm, wave after wave.

A huge wave reaching the roof of the cave stood in front of Revorno and smashed his head at him.

Revornor snorted, "The fragments of the Nightmare King, the commandment to liberate the world, the frozen black blade of nothingness, combined with my power and my body, together on the journey of destruction, even the souls of the gods have been crushed—God Annihilation!"

The magic gathered all his strength and slashed, scattering the waves, only to find that the waves were scattered to both sides and immediately boiled, and two water dragons pounced from behind him and crashed into the back of his heart.

Revornor threw out two god-killing balls to smash the water dragon, and another water dragon pounced on it from the side and swung his sword to scatter the water dragon.

At this moment, he suddenly felt the temperature in the air-raid shelter rise rapidly, and he was shocked: "What's the matter?"

Immediately after that, a dazzling purple light lit up in the direction of the entrance, and purple fireballs poured down the hole into the ground.

Revono said in his heart: "Attack with water first, and then use fire, don't the guys of the demon clan know that water and fire are incompatible?" But he soon found that he had misestimated the intelligence of Chongru, and Chongxu set fire not to attack, but to the silver nitrate solution in the boiling cave.

The Nine Abyss Flame is capable of releasing a high temperature of more than 3,000 degrees Celsius, while the boiling point of silver nitrate is only 444 degrees Celsius. The silver nitrate solution boiled instantly, and then sublimated into gas, and although the vampire's dark streamer wall could isolate the physical collision brought by liquid and solid, it could not stop the invasion of gas.

The vaporized silver nitrate smeared onto the vampire's skin, leaving a blister of blood on the edges.

At the same time, although vampires can maintain their physiology without breathing, they still complete their breathing movements at intervals due to the behavioral habits they have developed during the human period. During the wheezing process, they inadvertently inhale gaseous silver nitrate into their bodies, which immediately ignites their internal organs.

"Ah......h "Poof" they fell to the ground, falling into the silver nitrate solution.

The three marquis stopped breathing, while desperately condensing their magic power and improving their self-healing power to cope with the corrosion of silver nitrate on their bodies, while fishing for people in the water.

Although they chose the best way to deal with it at the first time, one count was burned to death on the spot, and three others were seriously injured, unable to heal themselves from the effects of silver nitrate, and they could not survive.

"Damn it!" Revornor was furious when he saw his descendants suffer from this. I think that his killing clan has been crisscrossing the world for more than 2,000 years, and he is the only one who kills others, and he has never been so aggrieved as today, and he was slaughtered by others in the "ditch".

He raised his voice and shouted: "What kind of ability is it to engage in these conspiracy tracks? ”

"Yo, when did the killer like to duel with people, but then again, didn't you use it as a conspiracy when you killed me?" said Chongxu as he appeared around the corner of the bomb shelter, showing a half-smiling face.

Revorno was taken aback when he saw the appearance of the heavy ruins, "Aren't you dead?"

"There are more people who want to kill me, and you want my life. Isn't it that easy?" He said lightly, but this operation of the Killing Clan did make him feel uneasy, if it wasn't for the clone to top the thunder, although he wouldn't have died, he would have been seriously injured. The vampires are attacking at this time, and the demons are in danger!

He secretly scolded himself for destroying the two vampire families and began to be self-righteous and careless, and he still had to be as careful as he was in the Demon Realm in the future.

Revorno suddenly realized: "It turns out that it was not the well-intentioned people who leaked the news, but the clues that the failure of the operation was seen by others." ”

Just yesterday, he awarded the Order of the Stalker to Duke Sith, who single-handedly planned to kill the ruins, and praised him for his great achievements, but now that I think about it, it's a joke: "Oops!

Revorno glared at Chongxu, gritted his teeth and said, "It doesn't matter if you're not dead. I'm now giving you a real taste of the horror of death. With that, he sprang into the ruins.

Chongxu pretended to be surprised and exclaimed: "Father, the devil is coming." "Turn around and run away. He was not far from the entrance of the cave, and he strode and boasted in an instant, and he escaped from the entrance of the cave.

Revorno was in a state of rage, and although he was not a reckless man, he relied on the courage of a master of the arts, completely ignoring whether there was an ambush outside the cave, and flew out.

But after coming out of the cave, he was immediately dumbfounded, and there were nearly a hundred demon descendants standing densely outside the cave.

The demons were in groups of three, two of them holding the nozzles of the fire hydrant in their hands, and the other was parked next to a three-wheeled electric vehicle, and the water tank was placed in the body of the electric car, which was actually dozens of mini three-wheeled fire trucks.

The tank of the fire truck was filled with silver nitrate solution, and with the order of the heavy ruin, the demon unscrewed the valve of the fire hydrant at the same time, "......"

At the same time, more than a dozen drones launched an offensive in the air.

Revornor secretly used magic to resist with a shield, wanting to use magic to repel the "fire" army, Chongxu changed his frightened appearance just now, revealed a fierce report, and came to him with the impact of the solution, and raised his hand is a stick, "Dirty creature, there is an old saying in the East that a strong dragon can't overpower the ground snake, you are not a strong dragon, but I ...... It's the head snake here. Die!"

Revornor fended off the continuous silver nitrate attack, and raised his hand to fight back, "Damn it's you!" swept his blood-red eyes towards the eyes of the heavy ruins.

Chongxu realized that he felt the strange aura in his eyes, realized that he must have been seriously implanted with the gene of the rabbit demon, and mastered the technique of fixing the pupil, so he hurriedly lowered his head and did not look at him, and made a false move to distance himself from him.
